Synchronization for Subsampling Digital UWB Receiver: a Holistic Approach

This paper evaluates in AWGN and dense multipath environments several time acquisition algorithms for digital pulsed UWB receivers sampling below Nyquist Rate for high speed communication. As UWB systems imply severe implementation challenges, we perform an interdisciplinary analysis of the design space by associating the system level assessment with an implementation perspective. Several architectures of the proposed algorithms have been rapidly prototyped on FPGA using a state-of-the-art design flow which can be extended to ASIC design.
